The prediction machine

Arne Dietrich:

"An emerging organizing theme in neuroscience is that the brain has evolved, fundamentally, to make predictions (Bar, 2007; Grush, 2004). The claim here is not that the business of anticipating events is one of the brain’s important chores, it is the main reason for having (big) brains in the first place."

"We can interact with the world in an infinite number of ways. Such complexity would quickly overwhelm us. So for behavior to be purposeful and timely in such a high-dimensional environment, the set of possible choices must be pruned. We accomplish this by continuously, automatically and, importantly, unconsciously generating expectations that meaningfully inform – constrain – perception and action at every moment in life (Llinás, 2009)."
